Either way, the "Star Wars" hero will visit the Queen City. Or at least, Peter Mayhew, who played the legendary Wookiee warrior Chewbacca, is.

Mayhew will be at the Cincinnati Comic Expo all three days.

Earlier announced visits: Marvel's Phil Coulson, a secret agent and member of the Marvel Cinematic Universe, is coming to the Cincinnati Comic Expo in September.

Actor Clark Gregg has long played the character, appearing in his slick suits and dripping with charisma in “Iron Man,” “Iron Man 2,” “Thor,” “The Avengers,” and the television series “Agents of S.H.I.E.L.D.”

That makes him "the longest screen time actor in the Marvel Cinematic Universe," according to a news release from Cincinnati Comic Expo.

Joining Clark is Cobie Smulders, who played Maria Hill in Marvel's "Avengers: Infinity War" and voiced Wonder Woman in the 2014 animated film "The Lego Movie." She also is known as Robin Scherbatsky in "How I Met Your Mother."

The expo already announced that "Game of Thrones" character Jaime Lannister, played by actor Nikolaj Coster-Waldau, will also be a special guest.

"The Cincinnati Comic Expo has been entertaining thousands of fans since 2010 while celebrating all periods and genres of pop culture with an emphasis on comics," the release reads.

It will take place from Sept. 14 to 16 at the Duke Energy Convention Center. Ticket prices vary and are available at www.cincinnaticomicexpo.com.
